I am only level 61 on my Samurai at this very moment I am typing this, but what is your rotation for AOE? I keep using Fuga, followed up by Oka, then Fuga again, followed up by mangetsu, and then I use Tenka Goken, but I always find myself TP starved in long aoe fights (even with Invigorate). Should I be getting the buffs in the middle for better TP management?

I ask this since I can't find anything about Samurai AOE rotation other than using Fuga, Mangetsu, Oka, and Goken.
